The Redmi Watch 2 Lite comes with a 262 mAh capacity battery and a magnetic charger. Redmi claims this battery can last up to 10 days under typical usage mode, and up to 5 days under heavy usage mode. The typical usage mode means that you don’t do any advanced sleep monitoring, disable the continuous heart rate monitoring and stress monitoring, and only use about 30 minutes of GPS tracking per week.
After the first day of testing with all the above-mentioned features enabled, the battery still retained 81% from the original charge. Even if you plan on using the watch heavily, you’ll probably go 5 to 7 days before you have to charge it again. If you only use the Redmi Watch 2 Lite smartwatch features, you might last longer. According to customer reviews on Amazon, the watch can last weeks on a single charge if you go easy on the advanced monitoring functions.
